Default host interface setting is Thunderbolt. The USB3+eSATA
is not applicable while host mode is Thunderbolt vice versa.
Thunderbolt and USB+eSATA cannot be used at the same time.
Please make sure you have configured the storage with the host
interface you want to connect before starting.
Before you start any operation, please make sure HDDs are installed properly into the
DVT10T2 enclosure
An alarming beep sound will be turned on if right number of HDD module was not
installed properly
Please make sure number of drives, RAID mode, and disk size were configured correctly
before starting to host connection.
For drive installation, please refer to Quick Installation Guide.
1.5.Connection and Quick Host Selection
＜Beginning of configuration＞
Please go through the quick installation guide to configure the device if necessary. The default
configuration of the storage is Thunderbolt host with full LUN size working at RAID 6 protection.
＜Steps for host connection＞
1. Thunderbolt connection (Default)
While Thunderbolt is enabled, both eSATA and USB3 ports are forced to disable state. (Default
operation might be varied per request from vendors)
The following Mac models are Thunderbolt 2 capable:
MacBook Pro (Retina, Late 2013 and later)
Mac Pro (Late 2013)
iMac (Retina 5K, 27-inch, Late 2014)
Mac mini (Late 2014)
Mac Computers (Mac OS® X v10.9.x or above) are certified.
Windows 8.1 hosts might be applicable but not certified as our official support.
Only one LUN is visible to host for Thunderbolt connection.
Any of two Thunderbolt ports can be used as host or cascade.
①Simply connect Thunderbolt cable from host to the Thunderbolt port of storage device.

BIOS AP Inc.
－9－
②Power on the storage device before turning on host system. In case, the device was not properly
configured, then an alarm might be turned on. Turn off the device and turn it on again while pressing
Mode button. Release the Mode button to see if LCD showed RAID Normal.
③The pre-configured LUN drive should be identified and popped up on your host Desktop screen for
first time without partition. If not, you might need to check if the device Thunderbolt was chosen as
the host interface or not. You can also check if any Thunderbolt device was attached on Mac
system. Please refer to Chapter 3.3 for volume partition on Mac operating system.
2. USB3/eSATA dual connection
First, please make sure eSATA was configured as Host interface in device parameter. Default is
disabled. Please read Chapter 2 about how to change the host configuration. Most of operating systems
should work with eSATA and/or USB3 host without having to install any driver. For hosts with UASP
supported on USB3, we strongly recommend you to enable it for higher performance. eSATA is
supported by OS inbox AHCI driver.
Window 8 or later supports UASP on native Intel USB3 port.
Mac OS® X v10.7 or later supports UASP on its USB3 ports.
USB3 can be enabled or disabled only host mode is set to eSATA. If host mode is set to
Thunderbolt, USB3 will be forced to disable state no matter parameter selected. The storage device
supports division of the configured disk capacity into single or two LUNs by LUN Mode and LUN Size
parameters. The details explanation and configuration can be found on Section 2.3
Case 1: Single LUN connection (default, LUN Mode: Direct no bias, LUN Size: Full)
①Simply connect host eSATA* or USB3 cable (if enabled) from host to the associated port of storage
device. (USB3 cable is included but no eSATA cable inside the package)
②Power on the storage device before turning on host system. In case, the device was not properly
configured, then an alarm might be turned on. Turn off the device and turn it on again while pressing
Mode button. Release the Mode button to see if LCD showed RAID Normal.
③Host system should be able to detect the disk immediately. Sometimes due to the delay of hard disk
initialization, you might need to rescan the device to see if the device shown later. If you still could
not find the connected device, you might try to re-insert the eSATA or USB3 cable on device or host.
Please refer to Chapter 3 for volume partition on different operating systems.
*eSATA is treated as a SATA disk and can therefore be connected to SAS HBA, too.
Case 2: Dual LUNs connection –eSATA and USB 3 (LUN Mode: Swap no bias, LUN Size: 64GB+All)
①Simply connect both eSATA* and USB3 cables from host to the associated port of storage device

DVT10T2
－10 －
②Power on the storage device before turning on host system. In case, the device was not properly
configured, then an alarm might be turned on. Turn off the device and turn it on again while pressing
Mode button. Release the Mode button to see if LCD showed RAID Normal.
③Host system should be able to detect two disks immediately, one as ATA device and the other as
USB device. If not, be sure to make sure parameter “LUN Mode”set as “Swap no bias”. For
example LUN Size is set to “64GB+ALL”, eSATA disk size will be 64GB and the rest of capacity will
be mapped to USB3 disk.
④To change host configuration, web-based management is recommended. Please read Chapter 2 for
necessary instructions.
Do not connect both USB3 and eSATA to the host at the same
time while LUN Mode is set to “Direct no bias”. This would cause
disk data corruption even it might not happen immediately.
3. Quick Switch between Host Interface
You can always configure the host interface mode through web GUI or LCD operation. For details, please
refer to Chaper 2. Starting from firmware ped101, we added a quick switch by using “INIT”button at the rear
panel. The location of “Init”button can be found at rear I/O besides eSATA connector.
Please do NOT switch the host interface while accessing is ongoing
You might want to unplug host connection first before switching mode
The storage was shipped with Thunderbolt host default.
①At normal operation, upper right corner of front LCD with “T” indicates host interface set to
Thunderbolt
②Press the INIT button about 3 seconds, then Buzzer will be alarmed shortly.At the same time
LCD will temporary show below to indicate the host transition.
③After releasing INIT button, upper right corner of LCD will show “U”indicating host is set as

Chapter 2. Setup and Monitor
2.1.Operation Overview
To simplify the process of setup, DVPro is designed to support all of setup options from front panel LCD
and button operation. The default RAID level is RAID6 for highest reliability. To prevent malfunction,
parameters cannot be changed at normal Monitor mode. The device needs to be in Parameter Setup
mode (Setup mode here after) to change parameters. The device works as its normal state at Monitor
mode while any error or status changed being monitored and dynamically reflected to its error indicative
functions such as LED light, buzzer alarm etc. Only if you wanted to change parameter setting, should
anyone choose to boot up the unit into Setup mode. A device reboot is required for mode change to avoid
mis-operate on front panel.
Critical parameters include number of drive, disk size, and RAID mode should have been pre-configured
with hard drives installed. If not, you will need to properly configure the critical parameters before the
device can operate normally. Default parameters, if any, are followed with “*” sign. Front LCD panel acts
as a short path for configuring the device yet Web GUI is more convenient and always recommended to
be used.
2.2.Introduction of Parameters Setup
This section explains the general parameters setup process.
To start with new configuration, the system has to be in Setup mode. Use one hand to press and hold
both “Mode”and “Select”buttons another hand to turn on the device. The LCD should show message as
below indicating the system in Setup mode. (The hold time of Mode and Select buttons is about 2
seconds; also the Init button at rear panel can be used to replace Mode and Select buttons)
